Chameleon

Changed

• deep-work hardened for weaker driver models, from a graded real --model sonnet run
  (10/10 on a pre-registered rubric, but with adherence slips that only fixture scale forgave):
  the comprehension ladder is now explicitly mandatory on trusted profiles (raw-reads-only is
  sanctioned solely for repos small enough to read whole, said in the brief); expert dispatch is
  a default with a stated exception rather than a silent judgment call; the rendered brief must
  visibly carry the ordered step plan, the unknowns re-audit line, and file:line evidence;
  editor-based guard flips are permitted only where a git flip cannot isolate the behavior, with
  the reason in the report; and finding-fate recording gets a mandatory report line plus
  per-finding decline reasons, so the precision ledger is fed instead of starved.
